I really like the perspective of a normal lens and have been toying with the idea of getting a 45mm ts-e for some creative uses. However, the lens is still expensive and pretty soft. It softer than the 24-70 version 1, way softer than the 50 1.8 even at f/2.8. I'm hoping they make it as good or better than the 50 1.4 at 2.8 and beyond.
